Abstract

This compass (100) comprises a fixing plate (110), suitable for being secured to the upright of a window frame, and a leaf support bar (120), suitable for being secured to a window sash frame, the support bar being articulated to the plate so as to project outwards, in the open position, the lower part of the opening. According to the invention, the plate has a lower part forming a pivot (140) cooperating with a support part (200) previously fixed to the upright of the frame, this part comprising a flared vertical groove receiving the pivot, the angular movement allowed between the pivot and the flared groove being sufficient to allow, during assembly, the insertion of the pivot in the groove despite an inclination of the support bar resulting from the opening of the compass and the approximately vertical position of the frame, which this insertion ensures taking up the weight of the opening, then folding the support bar vertically, so as to align the plate with the upright of the frame to allow these two parts to join together.

Description

The invention relates to a hinge

  compass-hinges (hereinafter called

  simply "compass") for Italian windows.

  An "Italian-style" window is characterized by the presence of a

  horizontal axis of rotation, real or fictional, located in the upper

  the window at the level of the amounts of the frame and

  opening (this axis of rotation, integral with the opening, may be

  you can move the amount of the sleeping frame); when opening

  rotation of the window around this axis, the opening (the leaf

  from the window) projects outward.

  Conventionally, the compasses for such windows comprise

  a mounting plate, adapted to be secured to the amount of a car-

  sleeping frame, and a leaf support bar, suitable for solid

  darisée to a window leaf frame, the support bar being hinged to the plate pivoting about a horizontal axis located

  at the level of the upper part of the frame so as to

  open, projecting the lower part of the

  this axis itself being mobile in vertical sliding on

  part of the length of the stage.

  Such a compass is for example described in FR-A-2 664 934.

  The problem which the present invention seeks to solve

the mounting of these windows.

  it is indeed common for building facades to be

  killed from curtain walls made from such windows to Italian-

  born; these, of great size, then have openings of

  significant weight, up to 150 kg.

  The assembly of the window is carried out by placing the opening on the

  frame of the window previously equipped with its frame The

  in advance, is then lifted from the outside, approaching the

  dormant and then secured to the latter by screwing on the

  of the frame of the mounting plates of the compasses equipping the

  ering. However, to allow the screwing of these mounting plates, it is essential that the compasses are in the deployed position, so that the screw holes of the plates are accessible Because of this, and because of the large opening angle between platinum and opening it to

  the moment of installation, it is necessary to present the opening (ie

  say the heavier part) in inclined position so that the mounting plate is exactly vertical along the upright. In practice, the opening rail, raised by a crane or other gear, is presented almost vertically in front of the frame of the frame, so with the plates oriented obliquely to the amounts of this frame The subsequent operations therefore requires the use of two people: one will swing the opening in order to tilt it and orient the platinum vertically, the other coming to screw this plate on the

amounts of the frame.

  This assembly is therefore inconvenient, uneconomical laying manpower, and also risky: because of the weight very important

  opening it, there are many opportunities to see it

  riser, bump against an amount, etc., before final fixing of the assembly Finally, the berthing maneuver, especially for

  very heavy opening, is very delicate to perform and the accos-

  is difficult to maintain accurately throughout the fixation process (ie until screwing

turntables be completed).

  One of the aims of the invention is to remedy these drawbacks by proposing a new compass structure enabling

  in place of the leaf, from the outside with mechanical means

  by saving the laying workforce and realizing

the operation safely.

  For this purpose, according to the invention, the compass is characterized in that the plate has, in its lower region, a pivot portion cooperating with a support piece previously fixed on the

  the frame, this support piece having a vertical groove

  wedge flared upward receiving this pivot portion, the angular movement allowed between the pivot portion and the flared groove being sufficient to allow, when mounting on the frame of the opening provided with its compass, first of all the insertion of the pivot portion in the groove despite inclination of the support bar resulting from the opening of the compass and the approximately vertical position of the frame of the opening, this insertion ensuring the recovery of the weight of the opening, and finally the vertical folding of the support bar, so as to align the plate with the amount of the frame to allow the joining of these

two pieces.

  Advantageously, the cooperating shapes of the plate and the support piece comprise, for the plate, a water drop relief projecting laterally towards the frame located opposite, and whose rounded part, which forms said pivot, is turned downwards and the tapered portion is turned upwards and, for the support piece, a

  vertical groove with a rounded bottom opening upwards by means of a

funnel me.

  Preferably, the support piece comprises, at the bottom of the groove, a

  vertical axis adjustment screw coming into contact with the surface of

tremité of the pivot.

  An example embodiment of the invention will now be described.

  with reference to the accompanying drawings.

  the invention, in the deployed position.

  Figures 2 and 3 are more detailed views, front and back

  wire, from the lower part of the compass system of Figure 1.

  both a frame frame, and a movable leaf support bar

  deployable at an angle c L relative to the plate 110 The bar-

  leaf support 120 is articulated to the plate 110 by means of a

  articulated parallelogram system 130 comprising: an inferior arm

  131, one end of which is articulated at 132 on the plate

  the other is at 133 at the lower part of the leaf support bar; a large link 134, articulated in 135 in part

  median of the arm 131 and, at its other end, in 136 to a slide

  bucket 137 movable in translation inside the plate (which is configured as a slide so as to guide and retain the slide 137); and a small link 138, also articulated at 136 on the

  slider and 139 at the upper part of the support bar 120.

  Oblong lights such as 111 allow the solidarity

  platinum to the amounts of the frame; in the same way, oblong lights such as 121 allow the joining of the

support bar 120 to the leaf.

  This structure, in itself classic as well as its kinematics,

  will not be described in more detail.

  In a manner that is characteristic of the invention, the lower part of the plate 110 is configured in a part 140 forming a pivot, intended to cooperate with a support piece 200 previously fixed on the

amount of the frame of dormant.

  These elements are illustrated in more detail in FIGS. 2 and 3.

  The pivot portion 140, that is to say the end of the plate

  of the compass, comprises an element 141, attached or monobloc, confi

  arranged to define a recess 142 which will cap the support piece 200 The element 141 comprises a relief 143 in the form of a drop of water (as can be seen in particular in Figure 3), with a rounded portion 145 facing to the support piece 200 and a part

  tapered 146 disposed opposite.

  The support piece 200, in turn, consists of a body 201 in which there is a vertical groove with a rounded bottom 202

  opening upwards by a funnel shape 203

  We will now describe, with the help of Figures 4 to 6, the assembly

  a window provided with a set of compasses according to the invention.

  In these figures, there is shown in 300 the frame of the frame whose uprights each receive a support piece 200, and in 400 an opening (leaf) provided with a set of compasses 100 whose ends are configured according to the invention in the way that we have

  Then (Figure 5), the opening 400, still vertical, is approached

  The opening angle has been chosen so that the end

  the lower part of the plate is well clear of the opening to facilitate

  the docking maneuver, with little risk of impact of the opening against the frame or the facade can be used for this purpose a removable block 500, visible in Figures 4 and 5.

pick up support pieces.

  it is then enough for the installer to exert a thrust on the bottom of the opening (arrows 600 in the figure) until setting the vertical of the

  mounting plate, which leads to the situation of Figure 6.

  The screwing can then be performed and the lifting means released (if this was not done in the previous step) The assembly is completed by adjusting the screws located in the lower part of the support piece

  200, definitive tightening of the plate and removal of the removable block 500.

  It can thus be seen that the assembly of the opening can be carried out entirely

  from the inside, with all the precision required and without

  risk, especially in the event of the operator giving up the

during assembly.
